Abstract
Utvidelses- og stabiliseringsverktøy for bruk i et borehull, omfattende et rørformet legeme (1) med et aksielt hulrom (2), og ved periferien spor som er innrettet med en åpning mot utsiden, et skjærebladelement (4) anbrakt i hver av de nevnte spor innrettet med i det minste to skjærebladarmer (5, 6) som er forskyvbare mellom en tilbaketrukket posisjon og en utstrakt posisjon, drivmidler (15) innrettet innvendig i det rørformede legeme, aksielt forskjøvet i forhold til skjærebladelementene, samt transmisjonsmidler som er i stand til å overføre bevegelsen av drivmidlene til de leddede skjærebladarmer, der disse skjærebladarmer, i den utstrakte posisjon, mellom seg og verktøyets rørformede legeme vil danne et rom (14) som er lukket i forhold til utsiden.Expansion and stabilization tools for use in a borehole, comprising a tubular body (1) with an axial cavity (2), and at the circumferential groove with an opening facing the outside, a cutting blade element (4) disposed in each of said grooves provided with at least two cutting blade arms (5, 6) which are displaceable between a retracted position and an extended position, drive means (15) arranged internally in the tubular body, axially displaced relative to the cutting blade elements, and transmission means capable of transferring the movement of the propellants to the articulated cutting blade arms, where these cutting blade arms, in the extended position, between themselves and the tubular body of the tool will form a space (14) closed relative to the outside.
